Hi, Honda heads, after changing the radiator and the thermostat 2 months ago, my temp gauge still rises to halfway temperature within a minute, is this normal ?? I have felt the top radiator hose and its screaming hot and the water/coolant levels seems ok nothing drastic, I have driven a couple hundred miles since the change and never noticed anything performance wise or mechanically dangerous happening, so I assumed this was normal, just want a little insight?
